GUY ANCHOR Filed Jan. 10, 1930 C. R. Pieper INVENTOR ATTORNEYS PatentedNov. 21, 1933 UNIT STATE testes? rarsNr FFl CE 3 Claims.

My invention relates to improvements in guy anchors, and it consists inthe combinations, con structions, and arrangements herein described andclaimed.

An object of my invention is to provide a guy anchor in whichimprovements over my Patent No. 1,123,368, issued February 5, 1915, areenibodied. In the present instance I provide a novel means whereby theanchor which comprises a 1 pair of operatively connected blades incombination with a spreader may be positively spread in such a mannerthat the blades will be properly centered during the spreading processand effectively associated with the spreader.

A further object is to provide a guy anchor in which means is providedwhereby the blades are expanded or opened evenly under all conditions.

Other objects and advantages will appear in the following specification,and the novel features of the invention will be particularly pointed outin the appended claims.

My invention is illustrated in the accompanying drawing, forming part ofthis application, in which Figure l is a side elevation of my deviceshowing the blades in their folded positions,

Figure 2 is a side elevation taken at right angles to the structureshown in Figure 1,

Figure 3 is a view showingthe blades in their expanded positions,

Figure 4 is a top plan view shown in Figure 3,

Figure 5 is a sectional view taken along the line 5--5 of Figure 4, andFigure 6 is a sectional detail view taken along the line 6-6 of Figure3.

In carrying out my invention, I make use of a pair of blades 1 and 2provided with rib portions 3. The blades are provided with semicircularend portions 4 which are bent outwardly with respect to each other asassembled in Figure 1. Each blade is provided with an enlarged portion 5having a recess 6 therein. Each bladeis also provided with a laterallyprojecting trunnion 7 15 which is aligned with its respective recess 6as shown in Figure 2. It will thus be seen that the blades are pivotallyconnected together. Each blade is provided with a pair of ribs 8 whichis disposed upon the side opposite the ribs 3.

The ribs 8 are curved as shown in Figures 1 and 3 and are provided witha recessed portion 9 whereby shoulders 10 are provided. It will be notedin referring to Figures 2 and 5 that the ribs 3 merge with flangeportions 11 of the blades. Each of the flange portions is provided witha of the structure (cries- 92) recess 12, see Figures 2, 4, and 5,which, when the blades are arranged in'their expanded positions as shownin Figure 1, provides a substantially circular opening through which ananchor rod 13 may extend. The blades are curved adjacent their flangesas shown at 11 whereby the blades have centering or aligning engagementwith the rod 13 at all times during the movement of the blades fromtheir positions shown in Figure 1 to their expanded positions shown inFigure 3. The anchor rod is provided with a spreader 14'. which isdisclike in construction. The rod fits snugly within the openingprovided by the recesses when the blades are expanded. The anchor rodmay I be provided with a threaded end upon which a nut 15 may be placedfor securing the spreader upon the rod. The spreader may of course besecured thereto by any other suitable means.

In Figure 5 I have shown the anchor rod as being provided with a loop 16permitting the rod to be connected with other mechanism, not shown.

In operation, the anchor is associated with the rod 13 and is loweredinto a hole in the ground slightly larger than the diameter of the con-7 struction. When the mechanism has been lowcred, the blades may bespread by tamping thereon with any suitable tamping tool, preferably atool of bifurcated construction. It will be seen in viewing Figure 1that when the blades are driv- I en downwardly, they will be caused tospread by reason of the spreader 14. The blades are therefore embeddedin the earth, and, when completely expanded as shown in Figures 3 and 1,the spreader will be disposed within the recesses 9 in the ribs 3,whereby the edges of the spreader will engage the shoulders 10. Suchengagement will positively hold the blades in their expanded positions,whereby the rod 13 will be efiectively anchored in the earth. Animportant feature in connec- A tion with my invention is the fact thatthe blades are provided with the flanges 11 and their associated curvedportions 11 which engage the rod 13 during the spreading process. Theconstruction is such that the blades are perfectly centered when thelatter are being driven into the earth. The blades in being properlycentered during the spreading process are positioned so that theshoulders 10 will always be properly aligned for engaging with thespreader 14. Thus it will be seen that the blades will always be lockedin their expanded positions when they are driven into the earth. Therecesses 12 form an opening conforming to the diameter of the rod 13when the blades are expanded.

In Figure 6 I have shown the ribs 8, associated with each of the blades,as being provided with a connecting portion 12 having a recess 12". Therecesses 12" receive the rod when the blades are collapsed as shown inFigure 1. The construction is also such that the blades may be easilyand quickly disconnected or operatively connected whenever desired.

I claim:

1. In an earth anchor of the type comprising a spreader plate and alongitudinal rod extending upwardly therefrom, and blades having contactfaces on their under surfaces for engaging said spreader plate when saidblades are forced down upon said plate to guide said blades intoexpanded position whereby the blades enter the earth edgewise, heelportions carried by said blades and closely encircling said rodthroughout the expanding movement, whereby the path and angularity ofeach blade is predetermined in all positions.

2. In an earth anchor of the type comprising a spreader plate and alongitudinal rod extending upwardly therefrom, transversely pivotedblades adapted to enter the earth edgewise, when forced down and out,contact faces on the under surfaces of said blades for engaging saidspreader plate when said blades are forced down upon said plate to guidesaid blades into expanded position, said blades having also portionsclosely encircling said rod throughout the expanding movement, wherebythe path and angularity of each blade is predetermined in all positions.

3. In an earth anchor of the type comprising a spreader plate and alongitudinal rod extending upwardly therefrom, blades pivoted to eachother on a transverse axis substantially intersecting said rod andadapted to enter the earth edgewise when forced down and out, contactfaces on the under surfaces of said blades for engaging said spreaderplate when said blades are forced down upon said plate to guide saidblades into expanded position, said blades having also portions closelyencircling said rod throughout the expanding movement, whereby the pathand angularity of each blade is predetermined in all positions.
